Sheriff's officials said the wife was trying to call the San Bernardino County Sheriff's Department when she was attacked.
"He struck her many times in the upper body, causing injuries to her face, her hands, her arms, and she had a fractured or broken arm," said sheriff's spokeswoman Cindy Bachman.
When her husband tried to intervene, the robber turned on him.
"He was also struck by the suspect and received some cuts," Bachman said.
Deputies received the call from the woman at 4:24 a.m. She told dispatchers that there was a man in her house in the 900 block of West 40th Street.
It is a small unincorporated pocket in north San Bernardino. The fortified home is surrounded by chain-link fences at least 7 feet tall that were pad locked Monday morning. Both cars parked in the driveway had handicapped license plates.
The robber was gone when deputies arrived.
It was an incident that upset relatives, primarily because of the victim's ages.
"They got beat up and this guy stole a bunch of things, including large amounts of money from my elderly father," said the couple's daughter, Sandy Gable, a Sonoma County resident.
The incident is also reminiscent of another violent home-invasion robbery that occurred in November, with tragic consequences.
In that case, 76-year-old Mary Beth Blaskey was found dead in her ransacked Fremontia Drive home. Her 2001 Lexus ES300 was missing, but police later found the vehicle abandoned on the northeast end of town.
It was one of three cases involving elderly victims that police have offered a $30,000 reward for information leading to arrests. But police say there is no evidence suggesting the same suspect committed each robbery and killing.
San Bernardino police Lt. Paul Williams said he suspects investigators will be talking to the Sheriff's Department to look at similarities in the cases.
"I'm sure that we will look into it," he said.
Bachman said she didn't know enough about the Blaskey case to say if there might be a connection.
"I can't say that there's any reason to believe that they might be related," she said.
